MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed .Tune 27, 1910. Serial No. 569,153.

To all whom it may concern:

Be it known that I, PETER CHRIsTMAN, a citizen of the United States, residing at Green Bay, in the county of Brown and State of Wisconsin, have invented certaln new and useful Improvement-s in Mechanical Movements;4 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a mechanical movement and has for its object -to provide mechanism for converting a reciprocating movement into a rotary movement or vice versa and at the same time to so construct and arrange the several part-s of the mechanism that they will mutually support and brace each other at all times.

The movement is applicable to all kinds of machinery having a forward and backward movement such as pump pistons, engines, lathes and the like or it may be used in any place where a crank has formerly been employed.

With these and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings Figure 1 is a side elevation of this improved movement; Fig. 2 is an end view thereof; Fig. 3 is a side elevation of one of the frame members carrying the stationary guides; Fig. 4 is a lorizontal section taken on the line 4--4 of In the embodiment illustrated two cross bars or plates A and B for supporting this improved movement form a part of a suitable supporting structure, (not shown) said movement being here shown as applied to a. pump rod C. A power shaft l is journaled in the cross bars A and B and is provided at one or both ends with a drive wheel or pulley 2. A gear wheel 3 is xed to the shaft 1 and is driven thereby for imparting motion to an internal oblong gear 4. The

side members of this gear 4 are provided on both faces with longitudinally-extending guides preferably in the form of ribs 5 and 5 which are designed to engage stationary guides as 6 and 6 formed on the inner faces of the cross bars or plates A and B of the supporting structure and which are preferbeing preferably fixed to a block D through which the piston rod C passes and at their upper ends they are fixed to cross rods 13 and 14 arranged on the cross bars A and B respectively and fastened at their ends to the supporting frame (not shown). Similar upright rods 7 and 8 are arranged in longitudinal alinement with the rods 7 and 8 and are fixed at their lower ends to cross rods 15 and 16 arranged on the cross bars A and B above and extending parallel with the rods 13 and 14. The upper ends of these rods 7 and 8 are secured to a fixed member of the supporting structure, (not shown). Crossheads 9 and 10 are movable vertically on the rods 7 and 8 and 7 and 8 respectively and are connected with the upper and lower ends of the internal gear 4 by means of pitmen 11 and 12 which are pivotally connected to the opposite ends of said gear 4 and to the crossheads 9 and 10 respectively. These boxes or crossheads are designed to reciprocate with said internal gear to hold it in an upright position while permitting it to move edgewise. The lower crosshead 9 is connected with the piston rod C to be operated as is clearly shown in Fig. 1. By the arrangement described the elongated internal gear 4 is held at all times in proper mesh with the pinion 3 so that when the shaft l is driven said pinion 3 transmits the rotary motion thereof to the gear 4 whereby said gear is reciprocated with the inner faces of the ribs 5 on one side thereof engaging the outer faces of the adjacent stationary ribs 6 and the outer faces of the ribs 5 on the other side of gear 4 engaging the inner faces of the ribs 6, and actuates the pump rod C or other machinery to be driven.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to wit-hout departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claim.

I claim as my invention A mechanical movement comprising a pair of stationary parallel horizontal bars spaced apart, each bar being provided on its inner face with a pair of vertical inwardly projecting ribs opposite similarly constructed and located ribs on the other bar, two pairs of horizontal rods t-he rods of each pair being in the same vert-ical plane and secured in and connecting the vertical ribs of each of the stationary horizontal hars, two pairs of vertical rods secured respectively to the upper and lower pairs of the horizontal rods, and projecting upward and downward in alinement with each ot-her, a crosshead slidahly mounted on each pair of vertical rods, an internal oblong gear between the stationary horizontal bars, pitmen connecting the crossheads with the ends of the oblong gear, a horizontal shaft journaled in the stationary bars, a gear secured on the shaft within the oblong gear of a diameter less than the transverse diameter thereof, and vertical ribs proj ecting laterally on each side of the oblong gear in position to co-act with the ribs of the stationary horizontal bars.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
